1. 打开新的窗口并传送参数: .BN~9w

接收参数: '}\{4Qst
string a = Request.QueryString("id"); O%? TxzX;
string b = Request.QueryString("id1"); (2J_Y*N~>

2.为按钮添加对话框 YT!QY@qw
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); XVwaX2=L
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 0l-m:6

3.删除表格选定记录 \2cbZQx
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; r,}U-S.w
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() bz!9\D|h
b;$ -s

5.点击表格行链接另一页 #BK\cIr
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) c_b^t09
{ 75vd ]45as
//点击表格打开 ;w1?EdaO
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) rtcY(5Q
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); fd >t9.

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; vp &jSfQ^

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); Sj(uc#

8.关于日期格式 B`<(qPD
7J./SBhB
日期格式设定 /L'm@8
DataFormatString="{0:yyyy-MM-dd}" %l[Cm4
3SVI|A5(d
我觉得应该在itembound事件中 kmNY
;b6Y$
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Df02#493

9.获取错误信息并到指定页面 IV;juFw}G
j[m\;3Sp
不要使用Response.Redirect,而应该使用Server.Transfer _)p@;vGV
Y1+4ppZ
e.g X_+`7yCi"x
// in global.asax Crh5^?
protected void Application_Error(Object sender, EventArgs e) { : RnjcnR
if (Server.GetLastError() is HttpUnhandledException) @5\OM#WT~&
Server.Transfer("MyErrorPage.aspx"); }lML..((1
sn2SDHY
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) B@e,3:
} @jN!j*Y H
zN#$eyt
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 LPb43
